• CVE-2026-107718: 0.28% estimated exploitation activity in the next 30 days; percentile 20.34 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Route parameters are inserted into generated URLs without URI encoding. When an application passes untrusted input to a route whose first path segment is dynamic, a value beginning with / can produce a scheme-relative URL. For example: This generates the following redirect: Browsers interpret this value as an external URL and redirect the user to https://evil.example.com. Details The shared createURL() helper is used by route URL builders, including Router.makeUrl() and Response.redirect().toRoute(). Route parameter values were appended without encoding: Wildcard parameters had the same behavior: The issue does not affect APIs that intentionally accept complete redirect URLs. Exploitation requires an application to pass attacker-controlled data as a route parameter and use the generated URL as a redirect destination. Impact An attacker may craft a link on a trusted application domain that redirects a victim to an attacker-controlled website. This can facilitate phishing and may be…

# Patch Next advisory brief: CVE-2026-107718

Advisory: AdonisJS: Unencoded route parameters can produce open redirects
IDs: CVE-2026-107718, GHSA-2m6q-8v3h-jqww
Record: https://patchnext.com/advisories/cve-2026-107718 (revision 3, source checked 26 Oct 2026, 13:07 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: @adonisjs/http-server 9.3.0, 8.2.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm @adonisjs/http-server: affected >= 9.0.0, <= 9.2.0; <= 8.2.2; fixed in 9.3.0, 8.2.3

## Suggested inspection (read-only)
- `npm ls @adonisjs/http-server --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on @adonisjs/http-server.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
